T 0 all wlwm z't mag] concem:

Be it known that I, CARL SIEHL, a citizen 0'I' the United States,residing at Ionia, in the county o1 Ionia and State 0f Michigan,

5 have invented certain 116W a11d useful I1n provenmnts in Buttons, 01which the followi.np; is a specification.

My invention re]ates t0 in1provement in huttons.

A11 important object 0f be inve ntion is t0 provide a button 01" simpleconst-ruction, und which 1nay be secured t0 fabric 01' the like in apositive and 1e1iable m2mne1fl Other objects and adwu1tages of theinvention Will be a i)parent during the c0urse 0f the followingdescription.

In the accompanying drawings forming a part of this specification, undin which 1ike numerals am employed co designate 1ike 20 parts throughotthe same,

Figu1e 1 is acenral vertical section through a butflon embodying myinvention.

Figure 2 is a perspective view 0f the head or outer member 0f thebutton, und,

Figure 3 is a, similar view 0f the retainer 01 inner nwmber 0f thebutton.

In the drawings, the numeral 5 designates thE heacl 01 0uter member o1the butt0n, which may be i01med of bone, composition, metal, 01' anyother suitzzble material. The outer su1face 6 nmy be in any suitableshape 01 d asign. The oute1 men1ber embodies z. shank 7., having aconvexed 01 spherically curvecl face S, t0 cont-aot Wi'l1h the fabric 9The shank 7 termumtes 111- 0x the 1ike. wardly 01 the periphery 0f themember 5), forming a flange 10.

The numeral 11 designates an inner retainer member, having sphericallycurved face 12, t0 conform to the curvature of the. face 8 f01 clampinga conczwed or the iabric 9 therebetween. The immer 0r retzuner member 11carries a screw-threaded stud 13, for inserti0n within a screwthreadedopening 14: in the outer member 5.

I is thus Seen that the maiximum contact area is provided between thefabrio and the spherically curved faces 8 and 12. bhus securelyclzimping the button to the fabric, und relieving the pull 0f the fab1icfrom the stud 13, which wuld tend so tear itQ It is t0 be understoodthatthe form of my invention herewith showriand described is 130 be haken asa preferred example 0f the same, and that various Changes in fihe shape,size, and arrangement 0f Parts may be resorted 130 without dep' artingfrom the spirit of my invention, 01' the scope 0f the subj0ined claim.

Having" thus desc ribed my invention, I claim% A separable button,consisting 0f. a head having 21 threaded borg formed centra]ly therein,a 'reducd shank formed 011 0ne side of said head, saidshank having itsend rounded t0 provide :1 semi-spherical surface,

a retainer member, a threaded stud cmrfled by said retaining memberadapted t0 be received in the threadedbore in Said head, the surtface ofsaid ret-ainer me1nber adjacent said semi-spherical -surface 0 f saidshank being Concaved a nd 0;E the .smne curvature &s the semi-sphericalsurfuce for binding a portion 0f thematerial therebetween to which thebutton is attached.

In testimony whereof, I have affixed my signat-ure in the presence 075two witnesses.
